HEEL OPERATED DRUM BEATER PEDAL APPARATUS Albert Sabo, Bloomsburg, Pa. Application February 11, 1952, Serial No. 270,933

Claims.

This invention relates to a heel operated drum beater apparatus and has for an object to provide such an apparatus for use as an attachment in beating a trap drum or operating a symbol.

A further object of this invention is to provide a drum beater apparatus that is here operated in contrast to the conventional sole operated drum beater apparatus.

A further object of this invention is to provide a drum beater apparatus wherein the drummer may rest the sole of his foot on a stationary base portion of. the apparatus and rest the heel of his foot on a pivoted depressable pedal so as to operate the beater against the drum by depressing his heel on the pedal and then return the beater to non-operative position by relieving the heel pressure on the pedal.

A further object of this invention is to provide a drum beater apparatus which is operated by the heel, thus enabling the drummer to beat the drum with much more ease due to the fact that he uses the muscles of his thigh in raising his leg and heel and then depressing it to operate the beater as contrasted with the conventional sole or toe pedal operated beater which is operated by the tendons of the shinof the leg, and thus is very tiring to the leg of the drummer. With shin operation of the pedal through the sole or toe, it is very difficult to operate the drum beater at a fast tempo, while the heel operating pedal of this invention may be operated very rapidly when needed without the extreme exhaustion that normally results from the conventional sole or toe pedal operated apparatus.

With the foregoing and other objects in View, this invention comprises the combination, construction and arrangement of parts hereinafter set forth, claimed and disclosed in the accompanying drawings, wherein:

Fig. 1 is a side elevational view, partly broken away, of the heel operated drum beater apparatus of this invention.

Fig. 2 is an end elevational view looking toward the right end of Fig. 1.

Fig. 3 is a left end partly fragmentary elevationofl 'ig. 1. 3

Fig. 4 is a fragmentary top plan view, partly in X-ray, of the heel pedal end of the apparatus.

There is, shown at-9 the heel operated drum beater pedal apparatus consisting of a base l0 having one end thereof formed into a pair of spaced apart clamp fingers cooperating with a clamp plate l2 which is pivoted at I 3 on a 2 U-bracket 4 and operable by a thumb screw l5 for clamping the apparatus to the drum hoop of a base drum or the like in a conventional manner, cushioning pads being provided, if desired, on the different surfaces of the clamp fingers II and clamp plate |2.

Secured to the base I0 adjacent its clamping end is the standard l6 consisting of a pair of spaced apart upright posts. Mounted intermediately on the standard It is the cross-bar l1. Oscillatably pivoted through the top of the standard I6 is a cross-shaft I8 journaled in the standard H5 at 20 and provided at one end with an off-set 2|. A tension spring 22 has one end 23 hooked over the cross-shaft oiT-set 2| and has its other end secured relative to the base M as by a screw 29 fastened in one of the posts of the standard IS. The tension spring 22 thus permits cross-shaft I8 to oscillate within its journals 2B but tends to restore it to the position wherein the off-set 2| is in the lowermost position. Secured about the midpoint of the cross-shaft I8 is a heater stem mount 24, the mount 24 being fixed relative to the cross-shaft l8 by means of a suitably located set screw passing through the mount 24 into gripping action with the crossshaft Hi. The mount 24 is provided with an aperture for receiving one end 25 of the beater stem 26, the drum beater 21 being mounted at the other end thereof. The beater stem end 25 is adjustably fastened in the mount 24 by means of a set screw 28 passing through the side of the mount into gripping contact with the stem end 25. Pivotally secured at 30 to the end of the mount 24 is an inverted wire shaped pull link 3|. A pair of spaced apart triangular shaped rocker arms 32 are pivoted at an intermediate angle corners 33 to the cross-bar H, and the lower ends of the wire shaped pull links 3| are each pivoted to the upper angle corners 34 of the rocker arms 32. The lower angle corners 35 of rocker arms 32 are each pivoted to a short leg 36 of a Z shaped lower pull link 31. The Z shaped pull link 31 has an intermediate arm 38 long enough to extend to the other end of the base i0, and has its other short leg 40 pivoted at 4| to the lower angle corner of a second pair of rocker arms 42.

The intermediate angle 43 of rocker arms 42 are pivoted to the ends of the legs 44 of a U shaped floating shaft 45 secured at 46 for oscillatory movement adjacent on the extreme end 41 of the base I0, this end 41 of base [0 having been reduced in width by being cut away at 48 to permit the lower pulling ends and their pivotal connection 4| to be depressed below the surface of the base H1. The upper corner of each rocker arm 43 is pivoted to the opposite sides of a heel pedal 5|, the other end of the heel pedal 5| being pivotally secured by a hinge 52 to a sole supporting plate 53, the plate 53 being supported on the base [0 and extending forwardly to between the posts of the standard it. Wear sheets 50 and are provided on the upper surfaces of the heel pedal 5| and sole plate 53, and may be removably secured thereto by suitable screws for replacement after extreme wear has taken place.

In operation, the base [0 rests on the floor after its clamping end has been secured to the drum to be operated by means of the-clamp fingers. H. and clamp plate I2 and the thumb screw I5.

The beater 21 is secured in position by its set screw 28 on the beater stem end 25, it being remov'dila st rage or shipment, The; drummer merely rests the S016$Qih51i00l3 on, the Wear sheet 55:. at the. sole plate 53?, and. rests, his: heel, on the wear pl te 54 of the heel pedal 5i.v To operate thetbeaiter against the drum, he merely depresses his heel, causing the heel pedal 51! to pivot down and; as viewed, in Fig. l, causingthe lower rocker 42/: to rotate, in a clock-wise direction while rotating: the U-shaped; shaft in a counterclockwise; direction, thus exerting rear and; downward pull: on the lower 2. shaped links; 321;.

This transmits a. similar: downward ancl. rear wand pull onzthe lower endsthaforward or arms; 3Q pivoting such. rocker arms about the cross-bar l1; and pulling, down the Y shaped pull linlr M to. thus: pull down ina clock-wise direction the outer end of the drum. beater mount and: rotate the cross-shaft t3. against the sistance of. the spring 22. This oscillates the drum beater stem. 28". to. cause the beater: Til to strike the drum, and relieving the pressure of the heel. on the heel: pedal wear plate permits the spring: 22: to rotate: the cross-shaft 1:8, in, the

opposite: direction withdrawing: the. beater from the drum; and restoring the pedal 5!: tic-its initial raised position ready iior another operation.

With this; construction, it is very easy for the drummer using: his. heel: raised. and, lowered by the thighmuscl'es to operate the beater against ,x

the: drum as fast and as often as desired without theusual extreme exhaustion ofiths conventional sole or too operated drum beater pedal.

While the device has. been. shown and the structure described in detail, it is obvious that this invention is not to be considered as bein limited to the exact form disclosed, and that changes in detail and construction may be made therein within the scope of what is claimed, withoutdeparting from the spirit. of this invention.

Havingthus set forth and disclosed th nature of this. invention, what is. claimed is 2.
